Answer:
the acceleration of harry is equal to 66.126 m/s²
Explanation:
given,
harry is 35 m behind Draco
speed of Draco = 40 m/s
original speed of harry = 50 m/s
acceleration = ?
time taken by the Draco
t =[tex]\dfrac{r}{u} =\dfrac{75}{40}[/tex]
t = 1.875 s
distance covered by Harry
d = 35 + 175 = 210 m
to calculate the acceleration of harry
[tex]s = u t+ \dfrac{1}{2}at^2[/tex]
[tex]210 = 50\times 1.875+ \dfrac{1}{2}\times a\times 1.875^2[/tex]
a × 3.516 × 0.5 = 116.25
a = 66.126 m/s²
hence, the acceleration of harry is equal to 66.126 m/s²
